The default scroll size we use for reading data from Elasticsearch is currently set to 50. We feel like this number is much too low for a default value. This PR increases the default scroll size from 50 documents to 1000 documents, parallel to the default scroll size used in Elasticsearch's reindex api.
This change is marked as breaking since it changes a default configuration value which may affect existing low memory Hadoop deployments that do not set this property.
